Digital sign network

The disclosed subject matter provides a digital sign with a video camera. The digital sign and video camera are connected via a communications medium to a central computer. The central computer provides a way of changing the images displayed on the digital sign and of disseminating the video from the video camera either through real time forwarding/viewing or recording the real time video stream and playing back the recorded video to a user. The central computer also provides a user interface where an authorized user, which would normally include an authorized governmental entity, can view the video stream and unilaterally interrupt the normally displayed image (or series of images) with an emergency notification message that would display on the digital sign.
